I have never used Roon, so I'm not (by ASR preference) much of a member here. I have read thru the Roon website, and it cannot tell me what I'm in for when I have music interfaces (in different rooms and purposes) of an iPad, a Windows PC, an Android Pixel phone, Amazon Echo, and I use Amazon HD Unlimited music service. These all play nicely together.
Roon tells me I should just download their free demo, and I will become all-wise. Well, folks, I did that with Qobuz last year, and I finally had to disconnect Paypal from my bank to STOP paying after I canceled the service -- THREE DIFFERENT TIMES. Qobuz kept replying that I didn't have a subscription, thus I couldn't cancel. Yet the bills kept coming and being paid by Paypal -- and me. I had to ask my bank to shut off all payments to Paypal to get rid of Qobuz. (That worked.) No more "download the free trial" for me.
Every Harvard, Yale, Stanford, or Wharton grad knows that the business model you want is the automatic monthly payment business. You know, monthly billings that go on forever. That's Roon's business model, so no. Yeah, Amazon keeps me paying for Prime, but I get a ton (literally) of free shipping for that.
So, bottom line, I don't have or think I want Roon, or Plex, or a Razberry Pi hobby. I'm not trapping my laptop to be a music player. So... no Roon, and I guess I'm a tight fit around ASR.
Bottom line: I guess I'm more into music than playback system tinkering. I can live with that.
